ABSTRACT

Peak expiratory flow rate is a useful test that can be performed quickly and simply at the bedside. Many patients whom the people encounter will already be familiar with the use of a peak flow meter, although they may not be using it properly. Commonly, the station involves teaching a patient, who has been newly diagnosed with asthma, how to use their peak flow meter. It is possible that the station may also include either inhaler technique and/or interpretation of peak flow results compared to a predicted value. The patient should be standing when they blow into the peak flow meter, and if available, they should wear a nose clip. Some patients will find it difficult to understand the description of what they are supposed to do. It is often worth demonstrating the technique to the patient, remembering that the people must change the disposable mouthpiece.
